Title: Control of nitrogen concentration in material argon
Inventor: MURATA AKIHIRO
IPC: F25J3/04
Filed: 1990-02-22
Abstract: PURPOSE:To improve the estimating accuracy of nitrogen concentration in material argon by a method wherein the discharge amount of product oxygen or material air amount is manipulated and the nitrogen concentration is continuously and automatically controlled to attain a preset value. CONSTITUTION:A relation between temperature and nitrogen concentration is previously obtained separately for each pressure value at each of specified steps in an upper part of an oxygen rectifying tower, the nitrogen concentration in material argon is obtained from the measured pressure and temperature and, according to the difference between an estimated value and a target value, the discharged amount of product oxygen and the amount of material air are manipulated, whereby the nitrogen concentration in the material argon is continuously controlled to attain the target value. Concerning the manipulation of the oxygen discharge amount and the material air amount, the manipulating amount is obtained by multiplying the deviation from the target control value and the value of state variable of an oxygen plant by the gain which has previously been obtained from input variables of the oxygen discharge amount and the material air amount and from a relation of response characteristics to the state variables of the oxygen plant such as the nitrogen concentration in the material argon and the temperature of the material air and the value thus obtained is continuously manipulated.

Title: Electric washing machine
Inventor: AIDA SHUJI
IPC: D06F39/08
Filed: 1999-02-22
Abstract: PROBLEM TO BE SOLVED: To prevent mixing of air from an overflowing water passage at drain time, and to reduce a noise at drain time of an electric washing machine by arranging a mechanism, for example, a check valve for preventing a backflow of drained water in a passage for making overflowing water flow from an outer tub. SOLUTION: At washing time, a drain valve 12 is closed by being driven by a motor, and water is gathered in an outer vessel 3. While, at dehydrating time, the drain valve 12 is opened, and the water from the outer vessel 3 is led out to the outside through a drain hose 13. By the way, a passage 14 for making water flow to the rear side of the drain valve 12 from the upper side of the outer vessel 3 is arranged in the outer tub 3 to prevent the water from wetting a floor by overflowing from the outer vessel 3. A backflow preventive mechanism 15 for preventing the water from flowing to the overflowing water passage 14 is arranged in a part for merging this overflowing water passage 14 and drained water. Mixing of air from the overflowing water passage 14 is prevented by this backflow preventive mechanism 15 to reduce noise at drain time.  This backflow preventive mechanism 15 may be constituted so as to be opened and closed by a check valve and the motor.

Filed: 1999-02-22
Abstract: PROBLEM TO BE SOLVED: To provide a thermal cooker which keeps foods from being excessively heated. SOLUTION: A microwave oven detects the temperature of a food within a heating chamber with an infrared sensor. When the detected temperature of the food reaches a specified value (Yes at S2), the maximum value or a mean of the detected temperature of the food as a turntable makes one turn (S4).

Filed: 1988-02-25
Abstract: PURPOSE:To suppress high-frequency noise leaking to the outside by electrically connecting a power input terminal through a capacitor to a cylindrical metal member for accommodating the secondary output line of an inverter circuit and shielding it in high-frequency. CONSTITUTION:As a power switch 9 is turned on, an inverter circuit 12 is operated for oscillation to lighten a fluorescent lamp 7 in high-frequency. In this case, high-frequency noise is generated in a lighting circuit, a part of the noise having a tendency to leak to the outside along a power line is absorbed by a LC line filter 14 and the noise leaking from the LC line filter 14 is absorbed by a capacitor 17 earthed in a metal pipe 4. Thus, the high-frequency noise leaking to the outside is reduced, thereby it is possible to improve the commercial output value.

Filed: 1990-02-23
Abstract: PURPOSE:To hold the origin position of a main body and the reference position of a body to be fitted in constant relation even if a thermal force, etc., is applied to a scale housing by fixing the point of the scale housing where an origin signal generating means is fitted to a body to be fitted and fitting both ends of the housing to the body so that they can be displaced only toward the scale main body. CONSTITUTION:When the scale housing 1 is applied with the force owing to thermal or mechanical variation, both end parts of the housing 1, i.e. cylindrical brackets 9a and 9b provided while extended from scale supporting members 3a and 3b fitted to both end parts are displaced toward the scale main body 2. Therefore, the origin position of the main body 2 is still fixed at the reference position (or zero point) of the body as it is, the relation between them is not changed at all, and excellent scaling is available. The main body 2 is also prevented from deforming and the scaling which is stable for a long period is available, since both ends of the housing 1 can be displaced.
